SAFETY-RAZOR.

Specification of Letters Patent.

Patented July 15, 1913.,

Application filed December 17, 1912. Serial No. 737,222.

T 0 all whomz't may concern Be it known that I, W'ILLIA J. BAUER, acitizen of the United States, and a resident of New York city, boroughof Manhattan, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Safety-Razors, of whichthe following is a specification.

This invention relates to safety. razors and the principal object ofthis invention is to provide a safety razor of inexpensive construction,the parts of which may be stamped outof sheet metal, the device as awhole, however, operating as efficiently as a safety razor of a moreexpensive and complicated construction.

A further object is to provide in a razor of this character, means forclamping the blade to its support, which means is firmly locked in placewhen the razor is clamped, but is readily unlocked to release the blade.

Further objects and advantages will appear from the detailed descriptionand the novel features will be particularly pointed out in the claims.

In the drawings accompanying this speci fication, Figure 1 is a sideelevation of a safety razor embodying my invention. Fig. 2 is aperspective view of the supporting and guard plate. Fig. 3 is aperspective view of the clamping plate.

The safety razor consists essentially of two plates 1 and 2 stamped outof sheet metal which clamp therebetween a blade 3. The latter is formedpreferably of thin, spring steel which readily flexes under the pressureof the clamping plates and is thus firmly clamped in position. The plate1 constituting the supporting and guard plate of the razor may bestamped out of sheet metal in one operation of a die. This plate isformed on one edge with a guard section 1 having the perforations 5through which the stubble projects and assumes a position in which itmay be readily attacked by the blade ed e. These perforations may beformed in the same operation in which the rest of the plate is stamped.At each end of the plate is formed an upstanding ear 6 having anaperture 7 which is adapted to receive the pivot of the clamping plate.EX- tensions 6 from the ears 6 present comparatively long surfaces whichserve as guides for the ends of the blade and keep it in properalinement. At the edge of the plate 1 opposite from the guard portion lis a raised curved portion 8 having perforations 9 therein adapted toreceive the locking projections of the clamping plate hereinafterdescribed. A raised ridge 10 is formed near the guard plate on which theblade rests as it is held down by the clamping plate. The blade issupported at two points, one adjacent to the junction of the raisedportion 8 with the body of the plate, and the other along the ridge 10.The raised portion 8 forms a shoulder against which the back of theblade may be positioned so as to place it in proper relation withreference to the guard plate. A downwardly extending tubular socket 10is preferably stamped out and expanded out of the body of the metal ofthe plate and is adapted to be fastened in any suitable fashion to theusual handle 10*. The clamping plate 2 is also formed of sheet metalwhich is stamped out in one operation. At one edge of this plateprojecting pins 11 are formed which are adapted to be inserted in theapertures 7 of the ears 6 of the supporting plate. At the other edge ofthe clamping plate, a tongue 12 is formed which curves around to conformto the curvature of the raised portion 8 of the supporting plate. A pairof projections or teats 13 are stamped out of this tongue and aredisposed so as to engage within the apertures 9 when the clamping plateis forced into locked position to clamp the blade as indicated inFig. 1. A downwardly projecting ridge let is formed also upon theclamping plate which is adapted to bear upon the blade and clamp itagainst the supporting surfaces of the supporting plate.

When the blade is properly positioned upon the supporting plate, whichis determined by the back of the same abutting the unct-ion of theoverturned portion 8 and the body of the supporting plate, the clampingplate is grasped by the tongue 12 and forced over the raised portion 8until the projections 13 lodge in the recesses 9. The spring of thesheet metal itself is sufiicient to give rise to the necessary pressureupon the blade for clamping the same firmly and also permits theyielding of the tongue 12 and the raised portion 8 to allow theprojections 13 to ride over said raised portion 8 until they are lodgedin locked position within the apertures 9. The tongue projects past theedge of the supporting plate sufficiently so that it may be readilygrasped and sprung outward to disengage the projections 13 to releasethe blade from the support. It will be noted that the line of contact ofthe razor upon the flat portion adjacent the shoulder and the crests ofthe ridge l0 and the guard member are substantially in the same plane,and when the blade abuts the shoulder, as it normally does, it occupiesthis plane and is in the position of finest adjustment, that is, givesthe coarsest shave.

hen it is desired to adjust the razor for a closer shave, the blade maybe moved slightly away from the shoulder against which the back of itabuts, thus moving the cutting edge forward into a position to come intocloser contact with the surface to be shaved. It will be noted that thesupporting plate is inclined from the ridge 10 tothe shoulder, and thuswhen the back of the blade is moved away from the shoulder, the edge israised somewhat and thus helps in obtaining the desired adjustment witha comparatively slight movement of the blade awa from the shoulder.

It will be thus seen that I have provided a safety razor of extremelycheap construction which is so formed, however, that it will properlyhold the blade and retain it firmly in position. This construction,although inexpensive, is as efficient and reliable as more expensive andcomplicated constructions.

Having thus described my invention, I claim as new:

1. A safety razor comprising two members between which a blade isadapted to be clamped, one of said members constituting a support havingan overturned portion on one side, two parallel ridges on the otherside, the outer ridge having perforations along its entire length andserving as a guard, and a flat inclined table between said ridges andoverturned portion, and the other member constituting a clamp having ade pending portion to press upon the blade, an overturned tongueextending over said overturned portion of the support and a projectionadapted to spring into and interlock in a recess in said overturnedportion, said tongue projecting beyond the edge of the support so as tobe readily grasped to disengage the same.

2. A safety razor comprising a supporting member, said member beingformed with a ridge having spaced perforations therein and serving as aguard, a second continuous ridge adjacent thereto, an inclined flat prtion adjacent said second mentioned ridge, the normal line of contactof the blade at the flat portion and the uppermost points of the twofirst mentioned ridges being in the same plane, ears formed on theopposite lateral ends of the supporting member, said supporting memberbeing adapted to receive the back of a razor blade on its inclined flatportion, a portion near the cutting edge of the blade on the continuousridge, and the portion immediately adjacent the cutting edge on theguard ridge, said edge being advanced and raised by movement of the backof the blade down the inclined portion, and receded and lowered bymovement of the blade up the inclined flat portion, and a clampingmember pivoted within the said ears of the supporting member, saidclamping member having means for interlocking with said supportingmember to clamp the blade in its adjusted position.

3. A safety razor comprising a supporting member integral throughout,provided with two parallel. ridges adjacent each other, the outer ridgehaving spaced slots throughout its length and adapted to serve as aguard, a flat inclined portion adjacent said parallel ridges, and anenlarged ridge forming 'a shoulder on the other side of said flatpontion and parallel to the first mentioned ridges, the junction of theshoulder and the flat inclined portion being in the same plane with theuppermost points of the two first mentioned ridges, said plane being theextreme position of adjustment in one direction of the razor blade, arazor blade movable upon. said supporting member in a direction down orup the inclined plane for advancing and raising the blade or recedingand lowering the same, an ear having an elongated base formed on eachlateral edge of said supporting member, said elongated bases serving toprevent lateral movement of the blade, a clamping member pivoted insaidears having a depending ridge contacting the blade and an overturnedportion having means for interlocking with the shoulder of thesupporting member to hold the blade in adjusted position.

Signed at New York city, in the county of New York and State of NewYork, this 13th day of December, A. D. 1912.
